SC627  
LED Light Management Unit  
Charge Pump, 4 LEDs, 700mA Flash LED,  
Dual LDOs, and SemWireTM Interface  
POWER MANAGEMENT  
Features  
Description  
The SC627 is a high efficiency charge pump LED driver  
using Semtech’s proprietary mAhXLifeTM technology.  
Performance is optimized for use in single-cell Li-ion  
battery applications.  
„
„
„
Input supply voltage range — 3.0V to 5.5V  
Charge pump modes — 1x, 1.5x and 2x  
Four programmable current sinks with 32 steps from  
0.5mA to 25mA  
„
„
Flash LED — 700mA max in flash mode, 250mA max  
continuous for spotlight  
Two user-configurable 100mA low-noise LDO  
regulators  
The charge pump provides backlight current in  
conjunction with four matched current sinks. It also can  
supply continuous or bursted current to a flash LED using  
the dedicated flash driver current sink. The load and  
supply conditions determine whether the charge pump  
operates in 1x, 1.5x, or 2x mode. An optional fading feature  
that gradually adjusts the backlight current is provided to  
simplify control software. A flash-timeout feature disables  
the flash if active for longer than 1 second. The SC627 also  
provides two low-dropout, low-noise linear regulators for  
powering a camera module or other peripheral circuits.

Charge pump frequency — 250kHz  
SemWireTM single wire interface — up to 75kbit/s  
Backlight current accuracy 1.5ꢀ typical  
Backlight current matching 0.5ꢀ typical  
Programmable fade-in/fade-out for main backlight  
External flash control pin to sync with camera  
Optional 1s flash time out  
Automatic sleep mode (LEDs off) — IQ = 100μA  
Low shutdown current — 0.1μA (typical)  
Ultra-thin package — 3mm x 3mm x 0.6mm  
Fully WEEE and RoHS compliant  
The SC627 uses the proprietary SemWireTM single wire  
interface. The interface controls all functions of the  
device, including backlight and flash currents as well as  
two LDO voltage outputs. The single wire implementation  
minimizes microcontroller and interface pin counts. The  
flash/spotlight output is triggered via either the SemWire  
interface or a dedicated pin.  
Applications  
„
„
„
Cellular phone backlighting and flash  
PDA backlighting and flash  
Camera I/O and core power  
In sleep mode, the device reduces quiescent current to  
100μA while continuing to monitor the serial interface.  
The two LDOs can be enabled when the device is in sleep  
mode. Total current reduces to 0.1μA in shutdown.
